Missing periods and now spotting

Hiya, im wondering if anyone has had the same experience as me. I came off the pill well over 2 years ago and my periods still aren't regular at all. I went for my usual smear test and it came back as inadequate and I need to go for another one. The reason it was inadequate was because of a cervical ectropian due to being on the pill for such a long time. I am due on my period and I have had all the usual cramping but I am only very lightly spotting. So lightly that when I wipe myself after I have been to the loo it's very light pink and hardly visibie. I am not pregnant cos my hubby had the snip years ago and I was wondering if anyone else has had problems like this? Thank you
